QUESTION 147 How is a SIP trunk in Cisco Unified Communications Manager configured for SIP precondition?

A. The configuration is done by selecting a SIP precondition trunk for trunk type. B. The configuration is automatically selected when RSVP is enabled for the location assigned to the trunk. C. SIP precondition is configured by selecting E2E for RSVP over SIP on the default SIP profile assigned to the SIP trunk. D. SIP precondition is configured by configuring a new SIP profile and selecting E2E for RSVP over SIP. The new SIP profile must then be assigned to the SIP trunk.

Answer: D

QUESTION 148 Which statement about SIP precondition is most correct?

When configuring SIP precondition, the IP phones and SIP trunk must have access to an RSVP agent. D. RSVP agents are only required for the IP phones. SIP trunks require RSVP agents only when fall back to local RSVP is configured. E. SIP trunk will always require RSVP agents regardless of what RSVP type is configured.

Answer: D

QUESTION 149 Refer to the exhibit. Assume that NANP is being used and 9 is used for PSTN access code Long distance national calls are preceded with 1. How should the HQ Cisco Unified Communications Manager be configured for calls to 3XXX to be sent to the gatekeeper at 1 0 1 6 1 with PSTN backups?

A. Configure a route pattern for 3XXX Assign this route pattern to a route list that points to two route groups. The first route group contains the H 225 trunk. The second route group contains the MGCP gateway with prefix digits 1 408555 for the outgoing called number. B. Configure a route pattern for 1#3XXX Assign this route pattern to a route list that points to a route group that lists the H 225 trunk as first choice and the MGCP gateway as a second choice. C. Configure a route pattern for 4085543XXX. Assign this route pattern to a route list that points to two route groups. The first route group contains the H 226 trunk. The second route group contains MGCP gateway. D. Configure a route pattern for 3XXX Assign this route pattern to a route list that points to two route groups. The first route group contains the H 225 trunk. The second route group contains MGCP gateway with prefix digits 91 408554 for the called number.

Answer: A

QUESTION 150 Refer to the exhibit. IT shows an H.323 gateway configuration in a Cisco Unified Communications Manager environment. An inbound PSTN call to this H.323 gateway fails to connect to IP phone extension 2001. The PSTN user hears a reorder tone. Debug isdn q931 on the H.323 gateway shows the correct called-party number as 5015552001.

Which two configuration changes can correct this issue? (Choose two.)

A. Add port 1/0:23 to dial-peer voice 123 pots. B. Ensure that the Significant Digits for inbound calls on the H.323 gateway configuration is 4. C. Add a voice translation profile to truncate the number from 10 digits to 4 digits. Apply the voice translation profile to the Voice-port. The configuration field “Significant Digits for inbound calls” is left at default (All). D. Add the command h323-gateway voip id on interface vlan120. E. Change the destination-pattern on the dial-peer voice 23000 VoIP to 501501? and change the Significant Digits for inbound calls to 4.

Answer: BE Explanation: Choose the number of significant digits to collect, from 0 to 32. Cisco Unified Communications Manager counts significant digits from the right (last digit) of the number that is called.

QUESTION 151 Which device is needed to integrate H.320 into the Cisco video solution?

A. video gateway B. MGCP gateway C. H.323 gatekeeper D. MCU

Answer: C Explanation: As with H.323 MCUs, H.320 gateways are provisioned in Cisco Unified CallManager as H.323 gateways, and then route patterns are configured to extend calls to these devices.

QUESTION 152 The following exhibit shows configs for H.323 gateway. You have been asked to implement TEHO from a remote branch office with area code 301 to the HQ office with area code 201 using Cisco Unified Communications Manager. The remote office has an MGCP gateway and the HQ office has an H.323 gateway. Once the call arrives at the HQ, it should break out to the PSTN as a seven-digit local call. Which statement about the route pattern is true?

A. route pattern should be 91201.[2-9]XXXXXX with Discard Digit as Predot and Prefix 9 B. route pattern should be 91201.[2-9]XXXXXX with Discard Digit as Predot C. route pattern should be 91201.[2-9]XXXXXX D. route pattern should be 9.1201[2-9]XXXXXX with Discard Digit as Predot E. route pattern should be 9.1201[2-9]XXXXXX with Discard Digit as Predot and Prefix 9

Answer: A

QUESTION 153 Which two statements about the functionality of a gatekeeper are true? (Choose two.)

QUESTION 155 Which statement about the function of a gatekeeper is true?
